I think it makes sense for Sony to charge for online since Microsoft would be foolish getting rid of it, since everyone in the console market basically expects to pay for it these days, but I expect there to be value adds to it from today's proceedings (some new hooks along the lines of Playstation+ or whatever the Gaikai aquisition was about).
Edit: or maybe you don't bring up the "you gotta pay for this" aspect of it til a later event.
I've recently jumped ship to the PC so the worries and disappointments and headaches of gaming are all behind me now. The consoles are nothing but trouble :(
It will be a sad state of affairs if the consoles become more headache inducing then pc gaming. I don't mean that from a "you plug this thing in and it works" perspective, but an integrates motion controls/touchpad integrated into the conrtroller/voice commands type of way. I am hoping Sony is making a better 360 (account-wise, social hooks-wise, trophies-wise) with a better take on a subscription service, but I fear the pandora's box that the Wii opened up of courting casual gamers via motion control gimmicks and now touchpads is something hardware makers will want to shoehorn into every platform.
